Summary: AskYourPDF adds multi-document chat

Why It Matters: This change lets users talk to many documents at once. This can make it easier to get information from lots of files.

What Changed:

• The main feature promoted changed from "generate detailed summaries" to "chat with multiple documents at once. Using our knowledge Base."
• The link for the main feature changed from /summarise to /documents.
• The text "Extract insights 10X faster from your documents." changed to "Say Goodbye to Endless Reading, Get Instant Answers from Any PDF".
• The text "Effortlessly interact with your documents. Chat, summarize, and manage all in one place to gain insights quickly and boost productivity." changed to "Ask any question, summarize, extract key insights, and ace your exams faster than ever."
